QLabel embedding in QStatusBar using Qt Designer

It is not possible with Qt Designer. I resolve it by creating label a in Qt Designer and later in constructor of my MainWindows add this line:

Ui::"class name of my MainWindows"::"name of statusBar Object"->addWidget("Object Name of Label");

In my application, the class name of mainwindows is MainWindowsForm, the status bar is named statusBar and the label is named informationLabel. Then I have:

Ui::MainWindowsForm::statusBar->addWidget(informationLabel);

I don't believe so. It's fairly simple to add one programmatically, though.

If you're just wanting to show a message, you could use: statusBar()->showMessage(tr("Message Here"));, or alternatively if you really needed a QLabel on the status bar, you could do something along the lines of:

QLabel *label = new QLabel("Message");
statusBar()->addWidget(label);

label would become a child of statusBar(), and appear in the first empty spot from the bottom left (addPermanentWidget(label) would add it to the first empty spot from the bottom right). If you place QLabel label in the classes header (or other var name), you'd be able to access the variable directly later (removing the initial QLabel type from the first line, of course).
